Interview
The department lead invited me to do the first round screening interview. She asked me some basic questions about my background and motivation, nothing too technical. She was very friendly and easy to talk to, and overall it was a very pleasant and encouraging conversation.

Interview
Quick process with maximum 2 steps:
First step includes an HR Call where they understand your interest in the role and availabilities.
Then they will invite you to an interview with the hiring manager and send you what you can expect in the interview. In my case, it was a case study and interview.
In the second step, the interview with the hiring manager happens where they will ask you regular interview questions (mostly behavioral) and you quickly present the case study you have worked on.
Keep the presentation very short and sweet but succinct!
Next step is offer/rejection.
